Description
Technical Field
The present application relates to the field of hardware upgrading technologies, and in particular, to a hardware version identification device, a hardware version identification method, and a hardware device using the hardware version identification device.
Background
In the prior art, general hardware includes a CPU, a logic unit, and various functional units. Due to the variety of hardware changes caused by the complexity of the design, more and more hardware version information needs to be identified, such as Printed Circuit Board (PCB) version, Bill of Material (BOM) version, BOOT (BOOT) version, Electrically Programmable Logic Device (EPLD) version, Field Programmable Gate Array (FPGA) version, and so on.
Therefore, how to clearly identify the change of different hardware version information and enable a user or an application layer to accurately obtain the current hardware version information is an important aspect of hardware design consideration. The current common methods comprise a direct identification method, a document or database management method and a software and hardware combined identification method.
Specifically, the direct identification method is to identify on the hardware surface, for example, display the current version of the PCB by screen printing the PCB, or attach a hardware information version tag on the carrier chip. When the direct identification method is adopted, logical sintering must be carried out through a configuration table or a configuration guide document, and version sintering is easy to be wrong due to slight negligence, so that the method has great obstacle to large-batch production conversion. The document or database management method mainly records some hardware version information solidified by characters into a document or a database. However, document or database management is generally inconvenient to use alone, and version management requires consulting of a corresponding document or database; when the hardware version information is updated or loaded, the hardware version information needs to be obtained by manual reference, and especially when the hardware version information is used in a large scale, human factors in an operation link become hidden dangers of reliability of the hardware version information. The software and hardware combined identification method is to identify the hardware information version through a single-board hardware circuit, and the corresponding service software identifies the hardware version information. At present, the common method of the method is to select the version of the corresponding hardware information by using a dial switch. The method has the following defects: the dial switch needs to be manually shifted to a corresponding position to indicate the current single-board hardware version information, and due to manual participation, the risk of errors is increased.
Further, the hardware version may specifically be read out by software after voltage division by using a voltage dividing resistor, and displayed in the system information. However, when the hardware version is upgraded, the voltage dividing resistance value needs to be recalculated, and then new resistance materials need to be added, which may easily cause uneven distribution of the voltage dividing resistance values corresponding to the hardware versions, and the whole voltage measurement range of the ADC (analog-to-digital converter) cannot be well utilized, and it is inconvenient to set the ADC detection range on the software.
